Room décor is the final and crucial part of its cosmetic completion. You are setting the mood for the room which has a very direct connection with its appeal to others, and therefore market value. Escape is appealing. Nothing is more calming than escaping from the world into the forest. Not only that, but with the surge of green awareness, nature themes are in. Make your space a happier place by getting close to nature.
Color scheme is key in a nature themed room. A major source of power for the forest is its ambiance. The overwhelming surrounding clusters of life, larger than we could ever imagine being. Go into the forest and do a 360. What do you see? Unless you are on a mountain, you see masses of indistinguishable greens and browns as far as you can see.
Your walls should have the same effect. Surround yourself in soft greens with brown accents. Darker greens appear heavy and sickly. You could even do a monochromatic color scheme with lighter green walls and richer green trim and accents.
For a beachy, or sunny look use warm orange hues.
Lighting should be composed of halogen and incandescent bulbs for the most natural looking light.
Fountains are a wonderful way to incorporate the water element into a nature themed room. Fountains can cost as little as $10 but can also be very expensive. Fountains typically come with a stone or rock element that will fit fine with your room theme. If not, it is easy to add your own stones. This will add visual appeal as well as a melodious natural sound.
Hammocks are a funky addition to a nature-themed room. This really gets back to basics and kids love them. Hammocks are inexpensive and easy to hang. Hammocks are also more comfortable than you probably think. I actually had a friend that used one, indoors, as a complete substitute for a bed for a few years.
Wildlife is a ingenious way of taking your room up a notch. You could get yourself another pet, like a bird, snake, or turtles. Or you could get framed wildlife. This could be framed butterflies or dragonflies. Also consider small animal skeletons, some come framed for you, like a non-traumatizing bat skeleton framed on the wall.
Plants are an absolute essential. Use large plants in pots and around the perimeter to create the foliage environment. Use flowers and smaller plants on tables. Remember to get hanging plants for the ceiling. Look for wall plant containers. This way you can have plants on all sides of you like the real forest.
